MIA, A GOEPGRATION 0F DELAVIARE oons'rnnorron Application filed Neve'mher 6, 1328. Serial 110. 317,581.

My invention relates to safe construction and more particularlyto safe protectmg devices.

in burglarizing safes, strong bones and the like burglars and robbers frequently attempt to burn away the metallic walls of the safe or strong box by means of acetylene torches. As the metal is burnt away the filling material is removed and entrance to a safe is frequently had through an entrance thus formed. The burning of such an opening through the metallic walls or a safe is accompanied by the heating of the surrounding metal and the fillingmaterial adjacent to the'opening.

I provide a safe or vault in WlllCll the walls contain a substance converted into a gas by the application of heat. A fuel may also be inserted ll the wall which ignites upon the application or" external heat for furnishing therinal energy to cause the generation and releaseof the gas. The gas is permitted to errculate, around the walls of the safe and pours out the opening being made.

The gas may have several characteristics such as a lachrymatory or crying gas; a sternutatory or sneezing gas; a fumigatory or poison gas; or a stenchatory or smelling ga The liberation of such gases either kills the burglars or renders them physically incapable of extending their operation of entering the safe. The same construction is also applied to safe doors.

The accompanying drawings illustrate the present preferred embodiment of the invention in which;

Figure 1 is a plan view in section of a portion of the wall of a safe and door,

Figure 2 is an edge view of a liner plate,

Fi ure 3 is a plan view of the plate, and

Figure t is a plan view in section of a modified form of the invention in which the gas forming substance is placed on the outside of the safe wall.

Figure 5 is a cross section of a safe wall on an enlarged scale.

A safe wall comprises an outer metallic wall 2, an inner liner or wall 4 and a body or filling material {iinterposed between the walls. The material 5 is usually a fire proofing material. A safe door 7 is mounted on the outer wall of the safe.

hinges 8 secured to an inner wall of the safe and comprises an operating mechanism 9 for 2 An inner liner 10 is disposed in spaced rela- 7 tion to the wall at for defining a space 11 therebetween. The space 11 is occupied by a perforated metal sheet 12 loosely filling the opening so that gas may circulate between the wall 4 and liner 10. The sheet 12 is coated with a chemical composition 13 containing a compound for liberating gas when subjected to heat and a fuel for furnishing such heat. The chemical compounds are applied .to the plate 12 either as a sheet or as a powder, as desired.

Upon the application of heat to the wall or door of the safe or vault, such as is caused by the application'of an acetylene torch or an electric arc, the heat penetrates the differ:

ent layers of the wall and raises the temperature of the plate 12 suihciently to ignite the fuel. The fuel thereupon burns inthe space between the wall 4 and liner 10 and liberates or generates gas. Thegas circulates through out the space and pours out of any opening made in the wall or liner. The effect of the gas upon the person attempting to enter the I safe depends upon the'nature of the gas.

Referring to Figure 4 a protective casing 10, corresponding to the lining 10 may be placed externally of the safe or vault if desired,'and a plate 12 coated with a gas forming substance placed between thecasing and The protective lining 10 or casing 10f may be applied to the doors and walls of safes or vaults already in service by adding an inner liner or outer casing to the safe walls already in service.

The fuel utilized on the plate may be any one of several kinds. Nitro cellulose compounds, gun powder mixtures, mixtures of gun powder and nitro cellulose compounds,

or any other combination of chemicals which when caused to react produce heat to vaporize the physiologically active chemical compounds in the mixture may be used.

The gas producing substances may beany one or a mixture of several types of such EEGNOR 230 FEDERAL LABORA-' compounds. If a lachrymatory or crying gas is oesired a chloroacetophenone compound known as CY may be used. If a sternutatory or sneezing gas is desired a diphenylchloroarsine gas may be utilized. Fumigatory or poisonous gases are hydrocyanic acid or cyanogen chloride. Stenchatory or smelling gases are mercaptaus, acrolein or chlorine.

It is to be understood, however, that other forms of fuel and gas producing substances may be used within the scope of the invention, as the foregoing examples are given by way of explanation of the invention and not by way of limitation.

lVhile I have shown and described the present preferred embodiment of the invention it is to be understood that it may be otherwise embodied within the scope of the appended claims.

I claim:

1. A safe comprising an outer wall, an inner wall, filling material between said walls, a casing spaced from one of said walls, a perforated plate of less thickn than the space between the wall and the ca arranged in said space, and a material adapted to liberate gas when heated supported by said perforated plate.

2. A safe comprising an outer wall, an

inner wall filling material between said walls, an inner lining spaced from said inner wall, a perforated plate of less thickness than the space between said inner lining andsaid inner wall arranged in said space, and a material adapted to liberate gas when heated supported by said perforated plate.

3. A safe comprising spaced metallic walls having filling material therebetween, a casing spaced from one of said walls to provide a space between the wall and the casing, and open-work support of less thickness than the space between the casing ano the wall disposed in said space, and a material adapted to liberate gas when heated, carried by said support. r

In testimony whereof I have hereunto set my hand.

JOHN WV. YOUNG.
